Prime Minister John Key is on a five-day trip to the United States which will end with an hour-long meeting with President Barack Obama at the White House.
Mr Key says he will use his meeting with President Obama on Saturday to promote the Trans-Pacific Partnership - the prospective regional trade deal involving both New Zealand and the United States.
Mr Key says he believes President Obama recognises the importance of the deal to the US in lifting its economic performance by opening markets to trade.
Mr Key will also meet Treasury Secretary Tim Geithner, Federal Reserve chairman Ben Bernanke and senior congressional figures.
On his way to Washington, Mr Key will stop in California where he will visit the internet companies Google and Facebook.
While in Los Angeles, he will have dinner with executives from Warner Brothers who did a deal last year to keep the filming of The Hobbit in New Zealand.
